Abstract
Due to the coupling action of vertical bending and torsion, horizontally curved box girders are subject to significant rotations as well as deflections. Installing intermediate external cross-frames between box girders is an effective means to control these displacements. A new parameter, deck unevenness ratio, is utilized in this study to quantify the degree of uneven deck caused by relative deflections and rotations. In order to assess the effects of external cross-frames on the deck unevenness ratio that affect deck slab construction, hypothetical twin-box girder bridges were analyzed using a commercial finite element program.
